Superior Source NO SHOT Vitamin B12 Instant Dissolve Micro Tablets go to work fast, bypassing the digestive system as they are quickly absorbed directly into the body under the tongue. This concept is critical for Vitamin B12 supplementation. With regular Vitamin B12 supplements, as much as 50% of the Vitamin B12 potency is lost in the high acid environment of the stomach. Our Superior Source Vitamin B12 formula with Vitamin B6 and folic acid is specifically formulated and manufactured to provide the maximum essential nutrients for the support of the heart. Vitamin D supports bone and dental health and promotes healthy muscle tone.
